High resolution measurement of aerosol equivalent scale heigth over wide range

Aerosol vertical optical depth (AOD) and horizontal extinction coefficient (AEC) have been measured with multiwavelength photometers at University of Granada, during the period 14 th -18 th July 2006. The AOD τ aer has been measured by using an Avantes USB2000 high grating spectrometer (440–900 nm, 1.5 nm resolution); at the same moment a FieldSpec has been used to measure Horizontal Aerosol Extinction Coefficient (AEC) σ aer in the range 400-700 nm , with a resolution of 1 nm. Both AOD and AEC were used to obtain an equivalent Ae rosol scale height at different wavelength in the range 440-700 nm , according to Mie scattering theory.
